MACHINE FOR COILiNG WIRE RODS.

SPECIFICATION forming part of Letters Patent No. 250,528, dated December6, 1881.

Application filed July 26, 1881.

To all whom it may concern Be it known that I, WILLIAM B. HAYDEN, acitizen of the United States, residing at Columbus, in the county ofFranklin and State of Ohio, have invented new and useful Improvements inMachines for Goiling Wire Rods from which to manufacture chain-links,rings, &c., of which the following is a specification.

This invention relates to certain improve- .ments in apparatus forwinding metallic wires or rods into spiral coils, either circular,elliptical, or other shapes in cross-section, and it is especiallydesigned for the preparation of wires or rods for the manufacture ofrings or links for chains, rings for haines, and for other purposes. y'

The objects of my invention are to provide certain means whereby a wireor rod may be wound circularly, elliptically, or in any other shape intransverse section, to be alternately formed into ringsor chain-links,as more fully hereinatter specilied. These objects I attain by theapparatus and mechanism illustrated in the accompanying' drawings, inwhich- Figure l represents a view, partly in forward elevation andpartly in vertical transverse section, of my apparatus; Fig. 2, a topview of my improved machine; Fig. 3, a longitudinal vertical section ofthe same; Fig. 4, a detached view of the former employed for theconstruction of the circular rings; Fig. 5, a detached view, showing aring cut from the wire or rod as circularly wrapped, Fig. 6, a detachedView of the former for wrapping the wire oval in cross section 5 Fig. 7,a front view of the said former; Fig. 8, a detached perspective view ofa link cut from the ovally-wrapped wire, and Fig. 9 a detached view ofone of the guides for directing the wire or rod forward from the former.

The letter A indicates, a strong table, of metal or other material, uponwhich the Working parts of my apparatus are mounted.

B indicates a horizontal shaft, journaled in the pillow-blocks O,secured to the table. The said shaft, at its rear end, is provided witha crank or pulley, D, or other means, by which it may be rotated, andthe forward end is provided with a chuck, E, for the reception oftheshank of a former, F. The said former consists 4of a short taperingmandrel of metal,

(Model.)

which is cylindrical, elliptical, or other shape in cross-section,according to the configuration to be given to the wire or rod. Theforward end ot' the former is slotted, as indicated by the letter G, inorder to seize and hold the end of the wire or rod.

The letter H indicates an adjustable slide, located in a longitudinalrecess, I, in the top of the table at one side of the horizontal shaft.The said slide is slotted longitudinally, as indicated by the letter L,and through said slot passes a clamping-screw, M, by means of which theslide may be secured in any desired position. The forward end of theslide is provided with a block, N, having a guide-aperture, P, throughwhich the rod or wire is passed to the former.. I

The letter R indicates a lever fulcrulned at S to the said block, and soarranged as to eX- tend transversely across the front of the table abovethe former. The said lever is slotted, as indicated by the letter T, andis provided with an adjustable guide, U, which is adapted to bear uponthe wire or rod on its way to the former. The said lever is also slottedat V,

and in said slot is journaled a iianged roller,

Y, directly over the former, the object of which is to bear upon thewire and hold it closely against the former, the flange directing thewire to and against a guide, 7, causing the wire to be projectedforwardly as it is coiled upon the former. The lever, at the endopposite its fulcrum, is bii'urcated or forked, as indicated by theletter A', and is provided with a link, B', by means of which it may beconnected with a spring, O', in order to hold the said lever and causeits guide and roller to bear with a yielding pressure upon the wire orrod. This rod B' can be screw-threaded at its upper end and providedwith a suitable nut or clamp thereon, whereby the rod can be held inadjustment in the slot.

The letter D' indicates an adjustable slide similar to the slide H, andlocated iu a longitudinal recess, E', on the opposite side of thehorizontal shaft. This slide is slotted and held in position by asetscrew,-F', and at its forward end is provided with a block, G', whichsteadies the end of the lever R. The guide W is secured to the forwardend of an adjustable slide, H', at a slight angle to the axial ICO lineof the former. a recess, I', on the bottom of the table, and is slottedat K and held in position by means of a set-screw, L.

The letter M indicates an extension projecting forwardly from the tableand secured to the bottom thereof'. This extension is provided with aslot, N', forming ways for the adjustable slide H. The said extension atits forward end is provided with avertical standard, R', having bearingsfor the journals at the forward ends ofthe guide-rollers S. Therearjournals have their bearings in the forward pillow-blocks of' thehorizontal shaft, and the said journals are provided withfrictionrollers, bearing against the periphery of the chuck, by means otwhich they are rotated. The said guide-rollers are parallel with theaxial lille ofthe former, and as the coil revolves keep itin shape andcause it to revolve with the former after the end has left the slot, asis necessary in forming coils cylindrical in shape.

The operation of my invention is as follows: The wire is passed directlyfrom the rolls through the aperture in the block at the forward endofthe adjustable slide, then under the guide and roller of the lever,and is secured in the bifurcated or forked end ot' theI former ormandrel. Upon rotating the shaft the wire is coiled upon the former, andthe coil as formed is constantly pushed forward by the guide WV.

When an elliptical or any other shaped coil other than cylindrical coilsare toA be formed the guide-rollers S, for receiving the coil t'rom theframe or mandrel, are dispensed with, and in lieu thereof the coilrevolves in a longitudinal trough or guide-way, S2, which is supportedby the trame-work of the machine. In this arrangement the mandrel orformer revolves the coil, even after the bent end ot' the latter hasleft the bifurcatcd end of the former or mandrel, such revolutionresulting from the ellipticalform ofthe coil.

The links or rings, when cut from the elliptical or circular coil, areof the form shown in Figs. 5 and 7, the particular form, ot course,

The slide H' is locatedin depending upon the shape of the former, andwhen the coil is so cnt up, which may ne done by hand or by machinery,the severed parts of cach link or ring are welded or otherwise unitedtogether ready for use.

The feeding of the rods directly from the rolls whichy produce the wireor rod to the former or mandrel may be accomplished by connecting therolls and the machine by a trougln-and hence, as the machineis automaticin its nature, skilled labor is not essential, and the cost ofmanufacturing links, rings, Src., for the objects specified will bematerially lessened.

Having fully described my invention, what I claim isl. In combinationwith the shaft and the slotted former, the adjustable slide andguideblock, the lever fulcrumed to said slide and provided with a guideand anged roller, and the spring and connecting-link,whereby the leveris held and the guide andtianged-wheel pressed against thewire or rod,substantially l as specified.

2. `In combination with the adjustable slide and guide-block, the leverand tor-mer mounted on the rotary shat't, the adjustable slide and blocktor steadying the lever, substantially as specified.

3. ln combination with the former mounted on the rotary shat't, theangedwheel journaled in the lever, and the guide W, arranged directly belowthe former and mounted on an adjustable slide, whereby the coil isprojected forward, substantially as specitied.

4. The combination, with the former, of the revolving rollers S',mounted in front of a'wire-v coiling machine to receive the wound coilafter it has lel't the former, as and for the purposes set forth.

In testimonyiv whereof I have hereunto set my hand in the presence oftwo subscribing witnesses.

WILLIAM B. HAYDEN.
